The combination of our Direct Drive System along with balancing the precise weight of our pedal arms, dual-action handlebars, foot pedal angle, and stride length, offers the perfect formula to assure the smoothest workout motion. This motion creates what we call the ?floating? effect. Once you reach a certain RPM, you start to ?float? and feel the smoothest possible motion. Once you try a Spirit Fitness CG800, we are confident that you will agree it is the smoothest piece of fitness equipment to help you achieve your fitness goals.
